Banjiman was quoting Suibhne O'Piobaireachd, Martin.
Talking of Suibhne O'Piobaireachd, I agree with you entirely on the subject of blacking up, but I still think you're being very unfair to those poor souls desperately trying to dance whilst backing up. Can you imagine the torment of trying to make like the Shropshire Bedlams whilst lugging around a faecal boulder the size of a rugby ball, that no amount of sphincterial manipulation will allow you to pass? We should pity the poor buggers and their aching bowels.
